Question

The mass of solute per 100 mL of solution is abbreviated as (m/v). Mass is not technically the same thing as weight, but the abbreviation (w/v) is also common. How many grams of sucrose are needed to make 915 mL of a 36.0% (w/v) sucrose solution?

The mass of solute per 100 mL of solution is abbreviated as (m/v). Mass is not technically the same thing as weight, but the abbreviation (w/v) is also common. How many grams of sucrose are needed to make 915 mL of a 36.0% (w/v) sucrose solution? Number g sucrose

Explanation / Answer

A solution with 1g of solute in 100 mL of final solution is termed as 1% or 1% (w/v).

In this case sucrose is solute. And 36.0% of solution means that there is 36% of sucrose in 100 mL of solution.

We need 915 mL of solution, therefore 36g * 915 mL / 100 mL = 329.4 g

329.4 g of sucrose will be needed to prepare 915 mL of 36.0 % (w/v) sucrose solution.
